What is the average size of each kidney?

  1. As big as a grapefruit

  2. As big as a basketball

  3. As big as an average fist

  4. As big as a tennis ball

The correct answer is: As big as an average fist

The average size of each kidney is roughly comparable to that of an average fist. This anatomical dimension helps in understanding the organ's functional capacity and its position within the body. Each adult kidney typically measures about 11 to 12 centimeters in length, about 6 centimeters in width, and 3 centimeters in thickness, which aligns well with the size of a closed fist. This size allows for an efficient filtration process necessary for removing waste and excess fluid from the bloodstream. Understanding this size is also crucial for assessing kidney health and diagnosing potential issues.
